I am trying to make up a fuel line for my engine. I have an RPC fuel pump which has 1/4" npt fittings. It got the adapter for a flare fitting and bent up some 3/8 hardline. The problem is the outlet on the RPC oump is different than an OEM pump and so I am having a tough time clearing the oil filter and the p/s pump return inlet. I need a very tight bend there but I can only do the bend so tight before the line collapses.

I am also having issue finding the room to run the line with the big 3/8 steel canister filter. I need some tight turns that I just can't make with hard line. And I don't what to use a big length of rubber hose to try and fit the filter. I might need to find a smaller 3/8 filter.

I have been considering using some AN type stuff but I have never used it before. I do see they have some nice tight elbows and bends that would make my job easy. And it looks like I can use compression fittings on hard lines. And of course I can use the braided stuff, but I have heard mixed reviews on the stuff.

on the fuel pump NPT fittings... you should be able to find that NPT to flare fitting in a brass 90* thread that into the pump with the flare end upwards you could put the filter in the rubber line from the frame to the pump (that's what i did)

edelman the brand here that has most of those fitting at the local parts store if you can't find that fitting in a 90 you could use a brass npt to npt 90 and screw the adapter into it.... if you can't find anything like that locally let me know i can check here at the parts store and maybe send it to you if necessary wish i'd have seen this post earlier, i was just there hangin' out like i always do b.s.ing and just helping customers

Thanks for the advice guys. Clocking the pump will make it worse. This was the best I could do with the inlet and exits. I think the 90 degree fitting should work. I will still need to make a pretty sharp bend, but atleast it's not like 270 degrees that I have to turn now. I called the local CARQUEST as I have bought Edelman fittings from them before. They didn't have one in stock but will order it up. I will pick up another length of hardline to try and make up a new line that will hopefully work better.

The other issue is the dual feeds. My carb came with an all rubber hose setup, which I am not a fan of. It worked fine, but now is the time to go to something better. It looks like a lot of the hard line dual feeds are cheap chrome piped ones, or AN types with braided hoses. Anyone have a recommendation for a decent setup? As you can see with my current setup, there isn't a lot of room for the current filter I am using. I can run the fuel line either in front of the distributor or behind (in the photo. But in both cases, I need to make a pretty sharp 90 with a small radius, which I can't seem to get with this large 3/8's hardline without kinking. I was thinking if I could get a 90 degree barbed fitting, that might help. I know I can get pex brass fittings, but it's not really barbed and not sure if it's a good idea for fuel.

Any thoughts on a good duel feed setup? Any thoughts on the fuel line routing?

2nd i've never not had a problem with the chrome plating on the inside of the flare of the cheap whammy lines. i've used a file & drill bit to remove the plating, it's pretty brutal but they sealed afterwards . that was before these new AN fancy pants kits they have now. a member going way back on the Old 351C forum had his own company making SS carb lines, this is him, http://grahamperformancetubing.com/products/products.htm

no personal 1st hand experience but he said his lines were the IDK?

Summit's search is so buggered i had to put keywords in the box to pull up this list,

thanks for the flashbacks LOL the cheapies with the regulator provision, that small port on the splitter ALWAYS leaks because they use a straight thread tap instead of a pipe taper so try to avoid that leaking pipe plug, maybe give an $11 delivered ebay special a try before dumping 10x that on a Percy's or QF Anodized Wonder Pipe? again, avoid the 1/8" port for a regulator!

i've had some pretty Uuugly supply rigs on my junk that i wouldn't go to any effort to reproduce but they worked at the time. i've become a big fan of the single feed carbs unless the dual is absolutely necessary to fulfill the performance requirements. i suppose the Holley transfer tube could be a smidge bigger but i guess as long as the secondary jets don't flow more than the tube it should be OK? besides i tend to run enough carbs to reduce the dependency on each needle & seat LOL

Thanks guys for the advice. I like those lines you posted Rock, I will have to see on the price and if the shipping to Canada isn't too crazy. Otherwise, I will probably go with the setup Johnny used. I like that one because it's short and it has a 5/8" inverted flare fitting. I could run a 90 degree elbow there with inverted flare on one end and a barb on the other. Then I could run the fuel filter and connect the other side the hard line which I can run up on the left side of the distributor. From doing measurements, it looks like it should fit with lots of room and be nice an clean. Otherwise, I will move the filter to the frame rail if that doesn't work.

In the mean time I do have the hardware to just run rubber hose to the carb from the pump (with a filter) if I need to.

Yeah if get the Holley setup, I'd get the one without the port. I can get the Holley parts locally. Those AN fittings would work too. I'd have to go that route if I get the Graham performance tubing setup as it doesn't have an inverted flare option for my carb.

My plan with the 90 degree turn is it would run the fuel line between the carb and the dizzy. There is tons of room there for the filter and the line, even though it doesn't look like it in the pic. I did a rough mock up and I think that will work and look pretty clean.

IDK what brand line is on mine it came with the carb i got used for $30 i think it had that pressure gauge port plug in it? i'd have to look... it don't leak if it does... now i'll have to go out and look as i'm curious!
